In listening to this tape, how do we know that the ATC Specialists advice was indeed correct?. If this aircraft had crashed would the ATC Specialist be sued for giving out this "advice"?. If this had happen in the UK would NATS protect its employees in court from subsequent legal action?. I think that we all know the answers to these questions. I think that it is in all our natures to try to help as much as possible a pilot in distress, particularly one as harrowing as this recording, but there are limits to our actions and responsibilities. I see no reason why ATCOs at the larger centres should have flight training as they do not deal with light aircraft, but the FISOs at ATC Centres should have flight training as a matter of course as they are more likely to deal with this kind of scenario.
